SAFETY WARNINGS SPECIFIC FOR
GRINDING AND ABRASIVE CUTTING-
OFF OPERATIONS
a. Use only wheel types that are
recommended for your power tool and
only for recommended applications.
For example: do not grind with the
side of a cut-off wheel. Abrasive cut-
off wheels are intended for peripheral
grinding, side forces applied to these
wheels may cause them to shatter.
b. For threaded abrasive cones and
plugs use only undamaged wheel
mandrels with an unrelieved shoulder
flange that are of correct size and
length. Proper mandrels will reduce the
possibility of breakage.
c. Do not "jam" a cut-off wheel or apply
excessive pressure. Do not attempt
to make an excessive depth of cut.
Overstressing the wheel increases the
loading and susceptibility to twisting or
snagging of the wheel in the cut and the
possibility of kickback or wheel breakage.
d. Do not position your hand in line
with and behind the rotating wheel.
When the wheel, at the point of
operation, is moving away from your
hand, the possible kickback may propel
the spinning wheel and the power tool
directly at you.
e. When wheel is pinched, snagged or
when interrupting a cut for any reason,
switch off the power tool and hold the
power tool motionless until the wheel
comes to a complete stop. Never
attempt to remove the cut-off wheel
from the cut while the wheel is in
motion otherwise kickback may occur.
Investigate and take corrective action to
eliminate the cause of wheel pinching or
snagging.
f. Do not restart the cutting operation
in the workpiece. Let the wheel reach
full speed and carefully re-enter the
cut. The wheel may bind, walk up or
kickback if the power tool is restarted in
the workpiece.
g. Support panels or any oversized
workpiece to minimize the risk of
wheel pinching and kickback. Large
workpieces tend to sag under their own
weight. Supports must be placed under
the workpiece near the line of cut and
near the edge of the workpiece on both
sides of the wheel.
h. Use extra caution when making a
"pocket cut" into existing walls or
other blind areas. The protruding wheel
may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
SAFETY WARNINGS SPECIFIC FOR
WIRE BRUSHING OPERATIONS
a. Be aware that wire bristles are thrown
by the brush even during ordinary
operation. Do not overstress the
wires by applying excessive load to
the brush. The wire bristles can easily
penetrate light clothing and/or skin.
b. Allow brushes to run at operating
speed for at least one minute before
using them. During this time no one
is to stand in front or in line with the
brush. Loose bristles or wires will be
discharged during the run-in time.
c. Direct the discharge of the spinning
wire brush away from you. Small
particles and tiny wire fragments may
be discharged at high velocity during the
use of these brushes and may become
imbedded in your skin.
d. Do not exceed 15,000 RPM when using
wire brushes
DO NOT WORK WITH MATERIALS
